## Updates from Braze
### 2026-01-23 00:47 UTC: investigating
Braze Engineers have identified elevated email bounce rates for customers sending email via SparkPost (Bird), starting around 17:35 ET. We are working with SparkPost Engineering who are aware and investigating the issue.
We'll update in 30 minutes or when we have an update from Sparkpost.

### 2026-01-23 02:00 UTC: investigating
Braze and Sparkpost engineers continue to investigate this issue. 
While we have not fully identified the root cause, Sparkpost is reverting a code deployment from this afternoon that we believe could be correlated. 
Our next update will come in an hour, or when the revert is complete.

### 2026-01-23 02:57 UTC: monitoring
SparkPost's revert successfully resolved this issue, and we have seen bounce rates return to normal levels, and no instances of the specific error code as of 9:42 PM ET. 
Our engineering teams will continue to monitor the situation to ensure the issue does not recur.

### 2026-01-23 03:42 UTC: resolved
We have not seen any instances of the specific error code in an hour, since 9:42 PM ET. 
This incident is considered resolved.
